Trifari

I acquired these two Trifari pieces a while back, from a friend who had a career dealing in antiques and estate sales. I am not entirely sure if there were earrings included in this set,originally, these two pieces are all I received. Both pieces are made of brushed silver, and are marked with the Trifari logo, that does not have a crown.The bracelet is hinged and bears a delicate clasp closure. The brooch has a straight pin with a locking closure. On one of the pieces , written in pencil, an unknown source made note of the date, 1983. Possibly, it could be the year it was made? Both the brooch and the bracelet are in impeccable shape, and most likely more valuable because of how remarkable they look!!If anyone knows anything about these pieces in particular, or the valu of Trifari jewelry, or anything that may help, please let me know!!! Thank you!!
